i think there's three ways to boost returns in a low returns environment. one is to look outside of mainstream. build a third pillar, if you will. we mostly rely on mainstream stocks and bonds. we have hardly anything in inflation sensitive assets and diversification into alternatives. secondly, look for alpha. try to find managers in strategies that can have value. fundamental index i think is a really important addition to that tool kit. thirdly, be tactical. when yields on bonds go negative or below the rate of inflation, which tacitly means negative yields, look elsewhere. >> bob, on that note. perfect place to leave it. we appreciate your coming by. bob arnott. >>> let's go to seema with a market flash. >> ringo is suing google over what it claims infringement of its search technology. a judge denied google's request for summary judgment and wants both parties to encage in settlements talks with the judge. that's what we understand. the stock up better than 35%. mark cuban has a big stake in this stock as well. >> thank you, seema. >>> this is a deal t
